How to Use the Air Conditioning in Wuling Hongguang S?
2 Answers
The method to use the air conditioning in Wuling Hongguang S is: Turn the A/C knob on the control panel to the left to activate cooling, and to the right for heating. The fan speed knob is located on the far right of the control panel, with 1 being the lowest speed and 4 the highest. Adjust according to the desired temperature. The automotive air conditioning refrigeration system consists of components such as the compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. The working principle of automotive air conditioning: 1. Compression process: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas before discharging it. 2. Heat dissipation process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser, where it condenses into a liquid due to the reduction in pressure and temperature, releasing a significant amount of heat. 3. Throttling process: The higher-temperature and higher-pressure refrigerant liquid passes through the expansion device, causing its volume to increase and its pressure and temperature to drop sharply, exiting as a mist. 4. Heat absorption process: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into a gas, absorbing a large amount of surrounding heat during the process. The low-temperature, low-pressure refrigerant vapor then re-enters the compressor.
I've been driving the Wuling Hongguang S to commute, and the air conditioning is quite simple to use: After starting the car, press the button on the center console with the A/C symbol to turn on the AC. Then, adjust the temperature knob to your desired cooling level—I usually set it around 23°C in summer. The fan speed switch is nearby; push it up for stronger airflow and down for weaker airflow. Too strong a breeze can cause headaches, so I recommend a medium setting. There's also a recirculation button—usually, turning on the internal recirculation cools the car faster, but prolonged use can make the air stale. Switching to external circulation for ventilation every half-hour is most comfortable. The Wuling's AC has manual temperature control, unlike high-end cars with automatic modes, but it's cost-effective and practical. Remember to clean the AC filter regularly, about every six months, otherwise, odors may develop and affect health. When parked under sunlight, open the windows to release hot air before turning on the AC, then close them and turn on the cold air for faster cooling.
